How do I answer in the interview about my 1099G? Me & my gf claimed our son in 2015. IRS caught it & I had to send fed return by mail. State adj. return.for 1 exemption.

It should have been 2 exemptions. Now I have to get a fed. transcript to prove to Ohio that I can claim 2.  So I really should have had a $242 refund instead of a $174.38. TT thinks I received a $242 refund.  How do I handle this? Thanks, in advance.
